The Centers for Medicare & Medicaid Services (CMS) said Tuesday that it canceled 315,000 Affordable Care Act marketplace plans covering about 760,000 people last month, citing unverified citizenship or immigration documentation and suspected improper enrollments, Reuters reported. The agency disclosed the cancellations in rulemaking documents published in the Federal Register.
Administration officials told The Wall Street Journal that the effort was led by the White House Task Force to Eliminate Fraud, headed by Vice President JD Vance, and that ending the subsidy payments tied to those enrollments would save an estimated $2.2 billion, according to a report citing the Journal. The savings figure is an administration estimate, not an audited result.
The action affects consumers as well as the brokers accused of gaming the system. Officials said many of the targeted enrollments were allegedly created without the consumer's knowledge, so some people may learn about a health plan, and a possible tax consequence, only when a cancellation letter arrives. For households that buy coverage through HealthCare.gov, the practical question is simple: Is the plan on file actually yours, and is the information behind it correct?
Timing adds pressure. Open enrollment for 2027 coverage begins November 1, and CMS is using an emergency rulemaking process to impose an immediate freeze on new agent and broker registrations, the same channel many families use to compare plans. CMS said brokers who do not already have a 2026 registration will be affected until February 1, 2027.
Who Was Targeted and What Happens to Brokers
Officials told the Journal the canceled enrollments fall into three groups: people who allegedly did not know they had been enrolled, people who had access to employer-sponsored coverage, and people whose income exceeded the limits for subsidized marketplace plans. CMS's own filing, as described by Reuters, pointed to unverified citizenship or immigration records and suspected improper enrollments.
CMS said it will bar about 569 brokers who it said "submitted statistically implausible rates of plan year 2026 applications" that lacked applicant information such as Social Security numbers. Administration officials separately told the Journal that CMS plans to terminate 469 agents and brokers after already removing 66 from the federal exchange. The reports did not explain how the two sets of figures relate. Officials also said 40 agents and brokers generated about 50,000 allegedly fraudulent enrollments, costing the government $45 million.
The agency also plans to review the immigration status and income eligibility of 415,000 current enrollees and to end a Biden-era policy that let some consumers keep receiving subsidies after they did not submit required eligibility documents, according to the Journal's reporting.
The broker freeze drew pushback from the industry. "A blanket moratorium on new agent and broker registrations would punish legitimate professionals instead of targeting the bad actors responsible for fraud," said Mychal Walker, president of the National Association of Benefits and Insurance Professionals, according to Reuters.
The crackdown builds on earlier steps. In late July, CMS Administrator Dr. Mehmet Oz announced that the agency would send notices of intent to terminate to 100 agents and brokers who had submitted unusually high numbers of 2026 applications without identifying information such as Social Security numbers, InsuranceNewsNet reported.
A Tax Bill Many Enrollees Never Saw Coming
The biggest household risk is often financial rather than medical. Marketplace subsidies are paid in advance to insurers and must be reconciled on the enrollee's federal tax return. CMS said improper broker activity, including enrollments made without genuine consent and plan changes made without permission, can trigger improper federal payments and leave consumers with surprise coverage changes, medical bill problems, or tax issues.
Florida shows how large a single scheme can grow. In April, AP of South Florida, a Florida-based brokerage, agreed to plead guilty in a case in which federal officials said its top executives fraudulently enrolled thousands of vulnerable consumers in fully subsidized plans, generating $141.5 million in unwarranted subsidies, according to the HHS Office of Inspector General. Its then-parent company, AssuredPartners, agreed to pay $135 million to resolve related civil allegations and was not criminally charged.
Florida and Texas are among the largest HealthCare.gov states, but officials have not released a state-by-state breakdown of the cancellations. Residents of states that run their own exchanges, such as California and New York, should watch for guidance from their state marketplace.
Wrongful Cancellations Remain the Central Unknown
Several key details have not been made public. Officials have not said how affected enrollees were notified, how long they have to respond, or how people who were enrolled correctly can restore coverage if their file was flagged in error.
The wider fraud numbers are also estimates. CMS said unauthorized enrollments could result in up to $6.6 billion in improper federal spending for the 2026 plan year. The agency told Fox Business in July that roughly 35% of marketplace enrollments may be illegitimate, a projection rather than a verified count. Enrollment climbed from about 10 million to more than 22 million during the Biden administration, a rise federal officials link partly to expanded subsidies and looser verification. Millions of people also dropped coverage this year after the extra COVID-era subsidies expired and monthly premiums became unaffordable for many, Reuters reported.
The people with the most at stake include low-income enrollees who answered ads promising free coverage or cash rewards, workers with seasonal or irregular income whose estimates may not match tax records, immigrant families facing status reviews, and anyone whose broker is terminated.
Steps Marketplace Enrollees Can Take Now
Log in to your HealthCare.gov account and confirm that the plan, household members, income estimate, and listed agent are correct. If you see a plan or broker you do not recognize, call the Marketplace Call Center at 1-800-318-2596 (TTY: 1-855-889-4325).
Open every letter from the Marketplace or your insurer, and respond by the stated deadline. Keep pay stubs, tax returns, and any employer coverage offer within reach, since those documents are the fastest way to answer an income or eligibility question. If you have access to affordable job-based coverage, you may not qualify for subsidies, and staying enrolled could mean a repayment at tax time.
Do not drop coverage in a panic. A cancellation tied to broker fraud does not by itself mean you did anything wrong. Anyone in ongoing treatment should confirm coverage before the next appointment or refill. If a caller demands payment or personal details about a canceled plan, hang up and contact the marketplace directly.

Key Questions Answered
What did CMS announce? CMS said it canceled 315,000 marketplace plans covering about 760,000 people last month, citing unverified citizenship or immigration documentation and suspected improper enrollments. Administration officials estimate the move will save about $2.2 billion.
Who was affected? Officials told The Wall Street Journal the enrollments involved people allegedly signed up without their knowledge, people with access to employer coverage, and people whose income was above subsidy limits.
What is happening to brokers? CMS said it will bar about 569 brokers and has imposed an immediate freeze on new broker registrations. Brokers without a 2026 registration are affected until February 1, 2027.
Could I owe money at tax time? Possibly. Subsidies paid for coverage you were not eligible for may need to be repaid when you file. People enrolled without consent should report it quickly and keep records.
How do I check my coverage? Log in to HealthCare.gov and review your plan, household, income, and agent. Call 1-800-318-2596 if anything looks wrong.
Should I cancel my plan now? Not without checking first. Confirm your eligibility, respond to official notices, and speak with the marketplace before dropping coverage, especially if you are in treatment.
